Backlight module

Abstract

A backlight module includes a back plate structure, a light source disposed in the back plate structure, at least one wire connected to the light source, and at least one wire fixing frame fixed on the back plate structure. Each wire fixing frame includes a main part, a first fixing part disposed on a side of the main part, a second fixing part disposed on a side of the main part and opposite to the first fixing part, and an extending part extending in a direction from the second fixing part to the first fixing part. A wire outlet is defined between the extending part and the first fixed part, and a wire inlet is opposite to the wire outlet. A wire hold space is defined among the main part, the first fixing part, the second fixing part, and the back plate structure.

       3. The backlight module as claimed in  claim 2 , wherein the back plate structure comprises a limiting bump, and the limiting bump is buckled with the recessed buckling member. 
     
     
       4. The backlight module as claimed in  claim 1 , further comprising at least one locking member, wherein the upper surface of the second fixing part has a fixing hole, and the second fixing part is fixed on the back plate structure through the fixing hole and the locking member. 
     
     
       5. The backlight module as claimed in  claim 1 , wherein the main part, the first fixing part, the second fixing part, and the extending part are one-piece formed. 
     
     
       6. The backlight module as claimed in  claim 1 , wherein the upper surface of the first fixing part is quadrangular. 
     
     
       7. The backlight module as claimed in  claim 1 , wherein the extending part is a rectangular block. 
     
     
       8. The backlight module as claimed in  claim 1 , wherein an end of the extending part is a rounded end. 
     
     
       9. The backlight module as claimed in  claim 1 , wherein a height of the first fixing part is lower than a height of the second fixing part. 
     
     
       10. The backlight module as claimed in  claim 1 , wherein a height of the extending part is equal to or similar to the height of the first fixing part. 
     
     
       11. A backlight module, comprising:
 a back plate structure, comprising a limiting bump; 
 a light source, disposed in the back plate structure; 
 a wire, connected to the light source; and 
 a wire fixing frame, disposed on the back plate structure, so as to position the wire by using the limiting bump and the wire fixing frame together, the wire fixing frame comprising: 
 a main part, comprising a wire accommodation slot on a surface facing the back plate structure, wherein the wire is positioned between the wire accommodation slot and the back plate structure; 
 a first fixing part, disposed on a side of the main part, and comprising a first limiting sidewall, a second limiting sidewall, and a step part, wherein the first limiting sidewall and the second limiting sidewall form an included angle, one side of the step part comprises a third limiting sidewall connected to the first limiting sidewall and the second limiting sidewall, the third limiting sidewall is substantially perpendicular to the first limiting sidewall and the second limiting sidewall, the other side of the step part abuts against the back plate structure, the limiting bump is buckled with the third limiting sidewall of the step part, and an inner edge of the limiting bump abuts against the first limiting sidewall and the second limiting sidewall; 
 a second fixing part, disposed on the other side of the main part, wherein the second fixing part is fixed on the back plate structure through a positioning member, the first fixing part further comprises two light leakage shielding pins disposed on two opposite sides of the step part respectively, and two side edges of the limiting bump are respectively supported on the light leakage shielding pins correspondingly. 
 
     
     
       12.
